- Size depends on household’s MPW and MPC
Define MPW
Marginal propensity to withdraw
- A measure of how much of ay extra pound earned is saved, taxed or spent outside the economy on imports
Multiplier = 1/MPW = 1/(MPS+MPT+MPM)
Define MPC
Marginal propensity to consume
- A measure of how much of any extra pound earned is spent within the economy
Multiplier = 1/(1-MPC)
What is the multiplier calculation?
MPC + MPW = 1
More MPW = lower multiplier
More MPC = higher multiplier
